  • INTERMEDIATE TRANSFER MEMBER RECONDITIONING
    Publication number: 20120141157
    Abstract: There is disclosed a method for reconditioning an intermediate transfer member and the reconditioned intermediate transfer member. The method comprises stripping off an outer layer of the intermediate transfer member. A mixture of a polymer, conductive particles and a solvent is coated over the outer surface of a seamless intermediate transfer member. The mixture is heated to form a layer on the outer surface of the intermediate transfer belt. An apparatus for reconditioning an intermediate transfer member is also described.

  • SIMPLE ITB STEERING RIB APPLICATOR
    Publication number: 20110135348
    Abstract: This invention provides a steering rib for an ITB. These steering rib or ribs are applied to the ITB by placing the rib around a cylindrical fixture. The rib is held in place by a vacuum that is applied to the rib to hold it against the fixture until the rib is adhered to the inside surface of an ITB. Once the rib or ribbing is adhered to the ITB, a series of apertures directs compressed air against the rib and the ITB to release them from the fixture.
